Acacia angustissima has potential as a fodder tree, but was toxic to sheep when fed without adaptation at levels higher than 50 g per day in previous studies. In the present study it was determined that rats are sensitive to anti-nutritional factor(s) of A. angustissima and can therefore be used ...

Evaluation of toxicity of Acacia angustissima in a rat bioassay
This work examined the ability of microorganisms from African ungulates to degrade 4-N-acetyl-2,4-diaminobutyric acid (ADAB) found in A. angustissima leaves, as well as purified ADAB and diaminobutyric acid (DABA). These microorganisms were taken from the rumens of bush duiker, eland, impala, Gra...
Sequences from a tannin-tolerant Selenomonas ruminantium isolate (EAT2) that hydrolyzes gallic acid were identified. Two exhibited identity to helicases with a wide phylogenetic distribution. PCR amplification by using primers from one helicase gene detected 2,000 to 5,000 EAT2 genome equivalents...

The experiment was carried out using a replicated (3x3) Latin square design with six sheep, to assess, the effect of supplementing maize stover fed ad libitum at three levels (100, 150 or 200 g) of Leucaena diversifolia. The sheep had an initial live weight of 26.4 kg (+ or -) 1.78 kg. In each pe...
